BACKGROUND ART

Along with rapid development of artificial intelligence technology and containerization technology, more and more artificial intelligence models are trained and tested on distributed resource management platforms. The existing artificial intelligence models are trained and tested using data sets, and different data sets are selected for application scenarios of different models.

DETAILED DESCRIPTION OF THE EMBODIMENTS

As mentioned above, in a task allocation method of a current resource management platform, the performance of each node itself is mainly considered, and statistics and analysis of the information of the data sets on the node are lacked, and the nodes are scored according to the current performance of the node itself during task allocation, so as to allocate tasks. Since the training and test of artificial intelligence models require data sets, therefore, when the training and/or testing tasks of artificial intelligence models are processed on the resource management platform, the resource management platform first allocates tasks to each node according to the current performance of each node itself, and then the node that obtains tasks downloads the data sets required for processing tasks.

However, since the data sets required for processing tasks often contain a large amount of data, these data sets are large, each nodes takes longer time during downloading, and needs more network resources, moreover, task processing may be initiated after the data set is downloaded, therefore, downloading of the required data set on the node will lead to a waste in time and resources, thereby reducing the efficiency in processing tasks.

Through researches, the inventor found that a lack of analysis of the data sets on the nodes in the task allocation method of the prior art leads to the above problems in task processing by the node, therefore, in the existing task allocation method of the resource management platform, the situation of the data set of the node needs to be taken into account. The information of data sets on each node needs to be acquired, wherein the information must include names of data sets of the node, to determine if the node has the required data set. Since the size of the data set required for each task processing varies, some tasks only require part of the data sets, while some tasks require larger data sets, therefore, the size of required data set of each node needs to be obtained, the node with the size of the required data set meeting preset requirements is selected during task allocation, to reduce downloading of the data set by the node. Therefore, through acquisition and analysis of information of data sets of the node, the tasks are allocated to a node with the required data set, thereby avoiding downloading of the required data sets by the node or reducing downloading of the required data sets, reducing the pressure on the network resource, and improving efficiency in processing tasks.

In order to enable those skilled in the art to better understand solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the accompanying drawings in the embodiments of the present invention, apparently, the described embodiments are merely a part but not all of the embodiments of the present invention. Based on the embodiments in the present invention, all the other embodiments obtained by those skilled in the art without any creative effort shall all fall within the protection scope of the present invention.

S102: acquiring data set distribution information of a plurality of nodes, wherein the distribution information of the data set includes names of data sets of the node and size of each data set.

It should be noted that, a plurality of nodes mentioned in the embodiment of the present application may be all the nodes in a resource management platform.

It should be noted that, the representation manner of the size of a data set in the distribution information of the data set is not defined in an embodiment of the present application, in a possible implementation manner, it may be specific numerical representation with the size of a data set. In another possible implementation manner, it may be a percentage accounted for the size of the data set in the total size of the data set.

It should be noted that, specific manner of acquiring distribution information of the data set is not defined in an embodiment of the present application, in a possible implementation manner, cached distribution information of the data set of the node is acquired from the unit in which related information is stored.

S103: judging if the node has the required data sets according to names of the data sets in the node.

It should be noted that, the specific way of comparison is not defined in an embodiment of the present application; in one possible implementation manner, the node has the required data set is judged through directly comparing the name of the data set required for processing tasks with the name of the data set in the node; in another possible implementation manner, the number corresponding to each data set is firstly preset, and whether the node has the required data set is judged through comparing the numbers.

S104: selecting a node with the size of the required data set meeting preset requirements for task allocation according to the size of the required data set in the node if the node has the required data set.

It should be noted that, preset requirement of the size of the required data set is not defined in the embodiment of the present application, and may be set according to actual conditions of task processing, wherein the preset requirement of the size of the data set may be different from the size of the data set required for task processing.

It should be noted that, as to task allocation to the node mentioned in the embodiment of the present application, allocation of different numbers of tasks may be performed according to actual conditions to each node to be allocated with tasks according to specific situation of each node and the situation that the node in the cluster has data sets.

In the present embodiment, artificial intelligence model training and/or testing tasks and names of data sets required for processing tasks are firstly received, and data set distribution information of nodes is required; secondly, the name of the required data set is compared with the name of the data set in the node; and finally, the node with the size of the required data set meeting preset requirements is selected for task allocation according to the size of the required data set in the node with the required data set. It may be seen that, by acquiring the information of the data set in the node, the node with the required data set is determined, and the tasks are allocated to the node with the size of the required data set meeting preset requirements, such that the tasks are allocated to the node with the data sets, thereby reducing the frequency of downloading data sets by a node allocated with tasks or reducing the size of the data set downloaded by a node, relieving network pressure caused by a large number of data sets downloaded by a resource management platform, reducing the time in downloading data sets by a node, and improving the efficiency of processing tasks on the resource management platform.

Second Embodiment

In the above first embodiment, a node with the size of required data set meeting preset requirements is selected for task allocation, and the size of the required data set of the node is difficult to be quantized. Moreover, during actual task allocation, when a cluster has a small number of nodes with the size of the required data set meeting preset requirements, according to the above allocation method, a large number of tasks will be easily allocated to a small number of nodes, thereby resulting in an excessive load on each node allocated with tasks.

Aiming at the above condition, the present application provides another task allocation method based on a resource management platform, and FIG. 2 is a flow diagram of another task allocation method based on a resource management platform provided in an embodiment of the present application.

The embodiment is described in details below.

S201: receiving an artificial intelligence model training and/or testing task and a name of data set required for processing the task.

S202: acquiring distribution information of the data set of the node sent by an agent unit, wherein the distribution information of the data set includes names of the data set in the node and the size of each data set.

It should be noted that, the agent units in the embodiment of the present application may be deployed on each node in a cluster, and are in one-to-one correspondence with the nodes.

It should be noted that, the data set distribution information in an embodiment of the present application may further include updating time of each data set and other information.

It should be noted that, the trigger time at which the agent unit sends data set distribution information of a node is not defined in an embodiment of the present application. In a possible implementation manner, when the agent unit detects a change in the data set on the node, such as under such conditions of newly adding a data set, deleting a data set and updating a data set, the new distribution information of a data set is sent.

S203: judging if the node has the required data sets according to names of the data sets in the node.

S204: obtaining a data set score of the node through a data set scoring strategy of the node according to the size of the required data set in the node, and selecting a node with the score meeting a preset score for task allocation.

It should be noted that, the specific data set scoring strategy of a node is not defined in the embodiment of the present application, and the data set scoring strategy may be developed according to the actual situation of nodes and task allocation in a resource management platform. In one possible implementation manner, the ratio of the size of the required data set in the node and the size of the data set required for processing tasks is computed and taken as a data set score of a node, and the node with the size of the required data set meeting preset requirements is determined according to the ratio of relative sizes of the data sets of each node.

S205: selecting nodes with the number of required data sets not meeting preset requirements or nodes having no required data sets for task allocation when the number of nodes with the size of the required data set meeting preset requirements may not meet the requirements for task allocation.

It should be noted that, the number of nodes required for a specific processing task is not defined in an embodiment of the present application, and the specific number may be set according to the processed task and the performance of each node.

It should be noted that, the selection strategy for nodes with the size of data sets not meeting the requirements or nodes which do not have data sets is not defined in the embodiment of the present application, and those skilled in the art may preset according to the performance of the node on the resource management platform and requirements for processing tasks.

In the present embodiment, the size of the required data set in the node may be accurately quantized through setting the data set scoring strategy of the nodes, thereby facilitating selection of the nodes; moreover, when the number of nodes with the size of the required data set meeting preset requirements is insufficient, the tasks are allocated to nodes with fewer data sets or nodes which have no data set, thereby avoiding excessive load of a single node caused by allocation of a large number of tasks to fewer nodes when the nodes with the required data sets are fewer, which may influence task processing.

Third Embodiment

In the above two exemplary embodiments, required data sets on the node are considered for task allocation on nodes. During task allocation, a larger node with required data sets is selected for task allocation, thereby ensuring to reduce downloading of data sets during task processing. However, in some conditions, larger nodes with required data sets may not meet requirements for processing tasks in terms of their own performances, nodes with the highest efficiency in processing tasks may not be selected under current conditions by only considering if nodes have data sets. Aiming at such a condition, the present application provides another embodiment of a task allocation method based on a resource management platform.

The present embodiment differs from the previous two embodiments as follows: for the selection of the node to be allocated with tasks, not only the required data set of the node is considered, but also the computing and storage capabilities of the node itself are taken into account.

In the present embodiment, anode with its own performance and the size of the required data set meeting preset requirements is selected for task allocation according to the performance of the node itself and the size of the required data set in the node.

It should be noted that, in an embodiment of the present application, the performance of the node itself and the size of the required data set in the node are not specifically defined, and the specific data of the performance of the node itself is also not defined, which may be set according to actual conditions of processed data.

It should be noted that, in an embodiment of the present application, the judgment of each performance in the node is not defined, in a possible implementation manner, the judgment may be realized through a well-set scoring strategy of performance of a node, and the total evaluating score of the node is obtained through computing a weighted value of scores with different performances of a node. It may be understood that, in another implementation manner, the evaluating score of the overall performance of the node may be further obtained in combination with a scoring strategy of the resource management platform itself and in combination with the data set score of the node.

In an embodiment of the present application, the performance of the node itself is further considered on the basis of originally considering the data set information of the node, the performance of the node is added to the consideration of the node, thereby ensuring that the selected node meets requirements for processing tasks in both its own performance and data set, and improving efficiency in processing tasks of the resource management platform.

Fourth Embodiment

A task allocation method based on a resource management platform provided in an embodiment of the present application is introduced below, and the method provided in an embedment of the present application is introduced below in combination with specific scenarios.

In the scenario, the resource management platform is Kubernetes, and algorithm technicians submit a training task of an artificial intelligence model to a Kubernetes resource management platform, and specify the name of the data set as dataset. An agent unit is set on each node in advance, and when the data set information of a node changes, the distribution information of a data set of each node is submitted to a resource management platform Kubernetes. Wherein the distribution information of a data set submitted by an agent unit includes the name dataset_(i) of the data set and the size datasize_(i) of each data set in the node, the size of each data set corresponds to the name of the data set and i represents the number of a node. The task allocation unit in Kubernetes judges if each node has the required data set according to the name of the data set in the node and the name of the data set required for processing tasks. The size of the required data sets in the nodes having the required data set is compared, and the node with the size of the required data set meeting preset requirement is selected for task allocation. Wherein, to facilitate selection of nodes, the node is scored according to a preset data set scoring strategy of the node. Since the Kubernetes resource management platform has a scoring strategy for the performance of the node, therefore, the node is allocated with tasks based on the original node scoring strategy of the Kubernetes platform and in combination with the data set scores of the node. According to the formula

${{size}_{i} = {\frac{nodeNum}{allNum} \times {datasize}_{i}}},$

the relative value size_(i) of the size of the data set in the node is computed; wherein nodeNum is the number of nodes with the data set in a cluster and allNum is the total number of nodes in a cluster. In order to prevent the obtained score of the nodes from being negative, the size relationship between the relative value size_(i) of the size of the data set of the node and the minimum value minsize of the required data set and the maximum value maxsize of the required data set is judged. Wherein, the maximum and minimum values of the required data set are set by the algorithm technicians at the time of task submission according to the actual situation of the processed task. If the relative value of the size of the data set of the node is less than the minimum value of the required data set, then the relative value of the size of the data set of the node is enabled to be equal to the minimum value of the required data set; if the relative value of the size of the data set of the node is greater than the maximum value of the required data set, then the relative value of the size of the data set of the node is enabled to be equal to the maximum value of the required data set. Since Kubernetes has the original node scheduling strategy, the score datascore of the data set of the node is obtained according to the formula

${datascore}_{i} = {\frac{{size}_{i} - {minsize}}{{maxsize} - {minsize}} \times {{weight}.}}$

Wherein weight is a weighted value of the score of the data set in the scheduling strategy of Kubernetes, and weight can take a value of 10. The obtained score of the data set of the node is added to the score of the original node of Kubernetes, for the node having no required data set, the score of the data set is 0, and a node with the score capable of meeting requirements for processing tasks is selected for task allocation. When the number of nodes meeting requirements is less, a node with the score not meeting requirements is selected. Moreover, after task allocation is completed, the size of required data set in each node is checked, and for the node having no required data set or the number of data sets being insufficient, the required data set is downloaded.

Fifth Embodiment

In some possible execution modes, the allocation unit may be configured to obtain a data set score of the node through a data set scoring strategy of the node according to the size of the required data set in the node, and select a node with a higher score for task allocation.

In some possible execution modes, the allocation unit is configured to select a node with its own performance and size of the required data set both meeting preset requirements for task allocation according to the performance of the node itself and the size of the required data set in the node.

The system may further include: an agent unit configured to send distribution information of the data set of a target node to an acquisition unit when the size of the data set of the node changes.

In some possible execution modes, the system may also include a rechecking unit, configured to check if the node has the required data set and if the size of the required data set meets preset requirements, and download the required data set if the node does not have the required data set or if the size of the data sets does not meet preset requirements.

The method according to claim 2, wherein, the data set scoring strategy of the node specifically comprises: computing a relative value size_(i) of the size of a data set in the node according to a formula ${{size}_{i} = {\frac{nodeNum}{allNum} \times {datasize}_{i}}},$ wherein i is the number of the node, nodeNum is the number of nodes with the data set in a cluster, allNum is the total number of nodes in the cluster, and datasize_(i) is the size of a required data set in the target node; judging the size relationship between the relative value size_(i) of the size of the data set in the node and the minimum value minsize of the required data set and the maximum value maxsize of the required data set; enabling the relative value of the size of the data set of the node to be equal to the minimum value of the required data set if the relative value of the size of the data set of the node is less than the minimum value of the required data set; and enabling the relative value of the size of the data set of the node to be equal to the maximum value of the required data set if the relative value of the size of the data set of the node is greater than the maximum value of the required data set; and computing the data set score datascore_(i) of the node according to the formula ${datascore}_{i} = {\frac{{size}_{i} - {minsize}}{{maxsize} - {minsize}}.}$
 4. The method according to claim 2, wherein, the method further comprises: acquiring updating time of a data set of a node; the obtaining the data set score of the node comprises: judging if the required data set in the node is updated before the task is processed based on the updating time of the data set of the node; if not, using the data set score of the node computed during the last task allocation.
 5. The method according to claim 1, wherein, the acquiring the distribution information of the data set of the node comprises: obtaining distribution information of the data set of the node sent by an agent unit.
 6. The method according to claim 5, wherein, the step that the agent unit sends the distribution information of the data set of the node comprises: when the data set of the node is changed, the agent unit sends distribution information of the data set of the node.
 7. The method according to claim 1, wherein, the selecting a node with the size of the required data set meeting a preset requirement for task allocation according to the size of the required data set in the node comprises: selecting a node with its own performance and size of the required data set both meeting preset requirements for task allocation according to the own performance of the node and the size of the required data set in the node.
 8. The method according to claim 1, further comprising the following step when the number of nodes with the size of the required data set meeting preset requirements may not meet the requirement of task allocation: selecting nodes with the number of required data set not meeting preset requirements or nodes having no required data sets for task allocation.
 9. The method according to claim 1, further comprising checking if the node has the required data set and if the size of the required data set meets the requirement for processing tasks after tasks are allocated to each node, and downloading the required data set if the node does not have the required data set or if the number of the data sets is insufficient. 10-15.
